Types of Valves Available at TVI
As a full-service plastic valve supplier, we offer a broad selection of thermoplastic valves to suit the needs of a wide range of industries and applications. Our available types of industrial valves include:
Industrial Butterfly Valves
Butterfly valves are shut-off valves that feature a relatively simple disc design. In the open position, the disc is moved out of the way and allows fluid to enter and exit the valve. When placed in the closed position, it prevents fluid from flowing through the valve.
These valves are suitable for fluid systems that require quick operation. Additionally, their simple, compact, and lightweight construction make them affordable and functional options for limited-space use cases. Typical applications for butterfly valves include use in water supply, wastewater treatment, gas supply, pharmaceutical, and food and beverage processing, chemical and oil, and power generation equipment and systems.

Universal Butterfly Valves
Universal butterfly valves are a variation of standard butterfly valves that allow for fewer disc positions. They integrate a spring-loaded latch lever to help set the flow control position. Industries that commonly employ this type of valve include the pool and spa industry.

Ball Check Valves
Ball check valves contain a ball that moves up and down inside a conical chamber using rails. Flow pressure lifts the ball, allowing fluid to flow through the valve. However, gravity causes the ball to return into place when the flow stops, preventing backflow.
These simple, low maintenance valves require an upward flow piping system to work properly. Typical applications include use in pumping stations with infrequent attendance and maintenance.

Swing Check Valves
Similar to ball check valves, swing check valves are valves that prevent backflow. They feature a design that uses a hinged disc to start or stop flow. The hinge design allows for flow in only one direction; the movement of fluid in one way opens the valve, while movement in the other way closes it. In contrast to butterfly valves, these valves do not require external activation.
Common use cases for these valves include water and wastewater pumping systems.

Wafer Check Valves
Wafer check valves operate similarly to swing check valves, allowing for fluid flow in only one direction. The flow of fluid through the valve lifts the thin wafer component off the seat. Flow in the other direction allows it to fall back into place to stop fluid from entering or exiting.
The unique wafer design makes them less likely to clog than ball check valves and suitable for horizontal or vertical mounting. Additionally, they require less back pressure to close.
These valves find application across a diverse set of industries, including chemical processing, mining, power generation, and water treatment. They are commonly used in tank inlet/outlets, pumps, mixers, and process intake systems.

True Union Ball Valves
True union ball valves use an open/close operation and can be activated manually or with a remote electric or pneumatic actuator. In addition, the safety block function doesn’t allow the ball to float downstream on pressure surges. TVI carries valves that are rated up to 235 psi, while other manufacturers only offer valves with a max of 150 psi. Our valves also include a 2 year warranty, ensuring long lasting quality and dependability.

Compact Ball Valves
Compact ball valves are ball valves with a smaller footprint that employ a lever actuator in place of flow actuation. Lever actuation either opens the valve or shuts off flow. These small plastic valves are suitable for any piping systems with limited space requirements.

Flange-Type Diaphragm Valves
Diaphragm flange valves are another type of unidirectional flow proportional valve that allows throttling and flow control. They use weir design diaphragms arranged in such a way as to allow for flow from downstream fluid pressure. The diaphragms collapse and close the valve against backflow pressure. This design helps provide bubble-tight sealing even in slurry and suspended particle applications.
Diaphragm flanges are often used in chemical processing to throttle the flow or as a flow control device.

Y-Sediment Strainer Valves
Y-sediment strainer valves help remove suspended solids and impurities in pumps, meters, and other fluid system components. They allow industry professionals to easily flush out accumulated solids during cleaning operations.
Common applications for these valves include chemical processing facilities, aquariums, mining operations, water treatment plants, and landfills.
